Expert Verdict

Ethoxylated surfactant; potential for trace 1,4-dioxane contamination from ethoxylation process (critical to test per NY DEC / California standards); mild irritation potential similar to other ether sulfates. Based on myristyl (C14) alcohol rather than the more common lauryl (C12); the longer chain typically yields a richer, creamier lather; synthetic/plant origin
